The synergist of the opponens pollicis is the abductor pollicis brevis. Both muscles work together to facilitate the opposition and abduction of the thumb, allowing for a wide range of thumb movements necessary for grasping and pinching. Additionally, the flexor pollicis brevis also assists in this function by providing flexion of the thumb.
What else can I help you with?
Which muscles is responsible for opposition movement of the thumb?
The muscles responsible for opposition movement of the thumb are the opponens pollicis and the abductor pollicis brevis. These muscles help bring the tip of the thumb in contact with the tips of the other fingers.
What muscle extends the thumb?
abductor pollicis longus,the extensor pollicis longus,and the extensor pollicis brevis
Is contraction of your opponens pollicis thumbs up or thumbs down?
It is making the "okay" sign.
What muscles form the thenar eminence?
The muscles that form the thenar eminence are the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis. These muscles are located at the base of the thumb on the palm side of the hand and are responsible for the movements and stability of the thumb.
What is the position of the thenar?
The thenar is the fleshy mass on the palm at the base of the thumb. It comprises the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis muscles. It plays a key role in thumb movements and grip strength.
Where are the muscles responsible for straightening out the fingers?
Abductor Pollicis Brevis, Flexor Pollicis Brevis, Opponens Pollicis, Abductor Digiti Minimi, Flexor Digiti Minimi, Opponens Digiti Minimi, Adductor Pollicis, Lumbricals, Palmar Interossei, Dorsal Interossei, Abductor Pollicis Longus, Extensor Pollicis Brevis, Extensor Pollicis Longus, Extensor Indicis, Flexor Digitorum Superficialis, Flexor Digitorum Profundus, Palmaris LongusThe muscles that flex your fingers are located on the anterior side of the forearm and hand. The muscles that extend your fingers are located on the posterior side of the forearm and hand.

Nerve supply of hand?
The radial nerve runs along the thumb-side edge of the forearm.It gives sensation to the back of the hand from the thumb to main knuckle of the back surface of the ring and middle fingers.The median nerve travels through carpal tunnel.Sensory branch to the thumb, index finger, long finger, and half of the ring finger.Motor branch to the thenar muscles(abductor pollicis brevis, flexor pollicis brevis, opponens pollicis) of the thumb.The ulnar nerve travels Guyon's canal.Sensory branch to the little finger and half the ring finger.Motor branch to adductor pollicis and hypothenar muscle(abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi).
What muscles help you grip?
Forearms. You can strengthen this muscle by putting both hands at chest height parallel to each other and opening you palm completely and closing them tightly. Do this repeatedly.
What nerve supplies the muscle on the radial side of the hand?
Of the muscles within the hand, the median nerve (C8, T1) commonly supplies two radial lumbricals, opponens pollicis, adductor pollicis brevis and flexor pollicis brevis. These all lie on the radial side. All other muscles of the hand are supplied by the ulnar nerve (C8,T1).
